Data, dictionaries and selection

Understand MV files and turn selected records into readable reports

01

One logical file, two complementary sides

The DATA side contains the application records: one item id and a dynamic array of attributes per item. The DICT side contains reusable descriptions of those attributes — names, headings, conversions, widths and calculated values. TCL query commands combine the two, so the same stored data can be presented differently without changing the records.
